Former USC and NFL football player Keyshawn Johnson was arrested early Monday at his Calabasas home on suspicion of misdemeanor domestic battery after reports of an incident involving his ex-girlfriend.

Johnson, 40, was taken into custody shortly before 1 a.m. when Los Angeles County sheriff's deputies responded to a possible spousal assault call.

Deputies "determined that the resident and his ex-girlfriend were involved in a domestic dispute," sheriff's officials said in a statement.

He gained notoriety in his Calabasas neighborhood last year for confronting singer Justin Bieber after allegedly seeing the pop star's car speeding through their gated community while children were outside.
